KEY RING AND KEY ENCLOSURE Filed Nov. 4, 1949 Patented Aug. 14, 1951 UNITED STATES ATENT OFFICE '6 Claims.

\;sion of an improved key supporting device hich will support a considerable number of keys of the small, short and flat type which are ernployed with locks having tumbler barrels. While the present key ring may be used for any type ci keys, they are peculiarly adapted to comf pletely enclose tumbler lock keys.

Another object is the provision of an improved key supporting device in which any key may be brought out of the housing and made accessible more easily, and in which the rest of the keys may all still remain completely enclosed.

Another obj ect is the provision of an improved key supporting device having a housing in which the keys may all be projected downward from the bottom oi the housing, while still connected to the housing, so that a selection may be made and by manipulating snap fasteners this selection can be brought to the top outside the housing while enclosing all the rest of the keys in the housing.

Another object is the provision of an improved key ring which has a spring lock adapted to keep it closed at all times so that there is no danger ci' losing the keys, but which is easily opened and to which keys may bev added orv subtracted without the labor that is incident to the usual circular key rings.

Other objects and advantages of the inv'enu tion will be apparent from the following description and the accompanying drawings, in which similar characters of reference indicate similar parts throughout the several views.

Referring to the single sheet of drawings accompanying the specification,

Fig. l is a front elevational View with the housing partially broken away, showing the key ring as it is arranged when one favorite key is disposed for immediate raccess and with the other keys completely housed;

Fig. 2 is an enlarged view of the ring showing the structure of the spring lock;

Fig. 3 is an expanded View of the housing showing the pattern from which it may be made and the shape of its parts;

Fig. fi is a sectional View taken on the plane ci the line lu-4 of Figure l;

Fig. 5 is a sectional view taken on the plane of the line 5 5 of Figure 1; and

Fig. 6 isa view similar to Figure 1, with the keys projecting from the lower end of the housing to permit selection or use.

Referring to Figures 1 and 2, the present key supporting device is indicated in its entirety by the numeral IIJ, and it preferably comprises a key supporting ring Il of special shape and an. enclosing housing I2.

The key ring II preferably comprises a partially circular portion I3 and a parallel sided portion I 4, terminating in a partially circular end portion I5, and is preferably made of the smallest wire possible while still having suflicient stock to form a trough I6 in one leg of the parallel sided portion I4. Having a ne -wire of stiff resilient material makes the ring applicable to all types ci keys, even the smallest ones having a small hole, and gives the keys the greatest freedom.

The partially circular portion I3 preferably has its lower side II flattened out so that a greater number of keys may be accommodated, such as from a dozen to a dozen and a half. The flattened bottom I1 is joined to the curved side walls. i8 and I9 at an easy bend 20 in each case, and these curved side walls are joined to the parallel legs 2i and 22 at another easy bend 23.

The upper end portion I 5 is half circular, and one of the parallel legs includes the portion 22 carried by the bottom of the ring and the trough IS carried by the top of the ring. The trough I6 is formed by means of a die which produces a split at 2 inside the trough portion I6 and also attens the wire out at this point, and shapes it into a U-shaped trough I5 which is adapted to receive the lower parallel leg portion 22.

The lower parallel leg portion 22 has a laterally turned end 25, which is turned toward the base of the trough and is adapted to pass through a round aperture 26 in the base of the U-shaped trough. The laterally turned 'end 25 extends .through the hole 26 only far enough to provide stock on the outside so that there maybe a head dening the locking groove 21, and the outer surface of this protruding bent end 25 is indi cated at 23 as being curved upward and downward so as to introduce a minimum amount of resistance to the passage of keys over this hump.

The parallel leg portion 22 is initially sprung outward and upward so that the resiliencey of the ring I3 tends to hold the parallel leg 22 in the trough I6, with the end. 25 in the hole 26, and in addition the ring pushes the groove 2l up ward until it receives the edge 29 of the base of the trough. This provides a lock which insures the ring against coming open and losing keys.

If the material of which the ring is made is not sufficiently resilient the result may, nevertheless, be accomplished by springing the bottom portion from time to time so that when it is open the bent end 25 and groove 21 assume the position shown in dotted lines in Figure 2.

The purpose of the ring portion I3 is to support'the keys and to provide the spring action necessary for the lock, while the purpose of the parallel sided portion i4 is to provide a protrudingportion of the ring that can be attached to a chain or the like, or for supporting a favorite key and to permit the keys to be pulled up into the housing or pushed downward out of the housing without separating the housing and ring.

The housing may be constructed of a single piece of flexible material, such as leather or imitation leather, according to the pattern shown in Figure 3. This comprises a pair of substantially rectangular portions 38 and 3| with angular corner cut-outs 51 at each corner joined together by a narrow neck portion 32, which is of sunlcient width to pass in between the parallel legs 2| and 22.

The rectangular portions 3|! and 3| are sepa= rated from each other on either side of the neck 32 by the inwardly extending grooves 33 and 34, and the neck 32 provides the fold at the top of the housing for constant engagement between the housing and the ring.

As the keys on the ring present a substantial thickness, the rectangular housing portions 3i! and 3| preferably include bodies 35 and 42, respectively; body 35 of suiiicient width to extend across the pack of keys and to be bent at 36 and 31 at right angles, and to provide an attaching flange 38, 39 at each side.

The attaching anges are provided with female snap fasteners 4i] and 4|. The other rectangular housing portion 3| has its body 42 of suf- Ycient width to span the pack of keys and is also bent at right angles at 43 and 44 to form a boxlike member, and has its inwardly extending at taching anges 45, 46 provided with a male snap fastener 41, 48.

At the bottom each body 35 and 42 is bent inwardly at a right angle at 49, 53, and the lower attaching flange 5| is provided with a female snap fastener 52. The upper attaching ange 53 is provided with a male snap fastener 54. As a matter of fact, the bends which have been described take place only when the snap fasteners are fastened, and the housing is made of one flat piece of material used and is bent and held to shape only when the snap fasteners are secured.

Thus if desired the user may leave one or more snap fasteners open, but the keys are still held within the boundaries of the leather cover and do not come in contact with the pocket.

The operation of the key ring is as follows:

When a key is to be added the snap fasteners 4|, 48 may be released on the side toward which the free leg 22 is presented. This opens the right side in Figure 1 of the housing I0, and any number of keys may be added by merely springing the leg 22 downward and inward and releasing it to the dotted line position of Figure 2.

When the keys have been added then the leg 22 is sprung back and released into the trough I6, and its end 25 will engage the trough above the hole 26. A slight downward pull on the ringV 4 while holding the U-shaped end I5 will cause the end 25 to snap into the hole 26.

The spring action of the ring |3 will then cause the groove 21 to move upward to receive the upper edge of the trough about the hole 26. The ring is now locked. When it is desired to move a favorite key to the upper parallel portion i4 of the ring, this can be done by opening both snap fasteners 40 and 4| and moving the keys upward and around the U-shaped upper part l5 until the key in question is reached. That particular key may then be retained, as shown at 55 in Figure l, while the stack of keys 56 may be kept down in the housing by merely moving them down on both sides of the ring.

When all of the keys are to be exposed, this isi done by merely pulling the housing upward on the parallel legs 2|, 22 until the narrow portion 32 of the housing hits the end l5, when the keyswill be exposed below the housing. Any key may' be selected and used in that position, or it may be moved to the top of the ring, as desired, by manipulating the snap fasteners.

The ring may be moved to the top of the housing, pulling all of the keys inside, and the lower snap fasteners 52, 54, may' close the bottom or, if desired, the bottom may be left open and the snap fastener flanges 5| and 53 may be used to extend the length of the housing.

It will thus be observed that I have invented an improved key ring and key housing which will support from a dozen to a dozen and a half keys of the tumbler type in a very compact condition, surrounded by leather, imitation leather or some other suitable fabric, preferably relatively stiff yet flexible, so that they cannot wear outthe pocket.

While a key is being used, as, for example, anl ignition key, it can be brought to the top of the ring outside the housing and the rest of the keys will depend from it, while still enclosed in such manner that they will not rattle.

The present key ring permits easy manipula--l tion of the keys because it is made of relatively thin wire of resilient material, such as spring steel or spring brass. The key ring is durable, safe, economical and may be used for a long period of time without losing keys or without.

necessity for repair or replacement of any of its parts.

While I have illustrated a preferred embodiment of my invention, many modifications may be made without departing from the spirit of the invention, and I do not wish to be limited to the precise details of construction set forth, but desire to avail myself of all changes within the scope of the appended claims.
